Study Notes
Transformers
- A common characteristic of a step-up transformer is that it increases the voltage of an alternating current.
Magnetic Storage
- A magnetic disk has the advantage of faster access time and random access capability over magnetic tape, which has sequential access.
Phasors
- X leads Y by 270 degrees represents a phase shift of 270 degrees or 3π/2 radians.
Integrated Circuits
- A disadvantage of CMOS (Complementary Metal-Oxide-Semiconductor) is that it can be susceptible to electrostatic discharge damage.
Brushes
- Carbon brushes are preferred over copper brushes because they are less likely to spark, which can be a safety issue in certain applications.
